Exercising my inner idiot

Now that the water in our pool is too cold for me to swim regularly, I thought I'd try a treadmill. So Gary and Colter and I headed to Play It Again Sports last weekend. I walked around a bit, checked out the machines, then stepped on one. I flipped the switch and went flying. I lost my shoes, skinned my knees, yelled "Help!" until Gary finally stopped laughing and turned the machine off, and generally felt like an idiot. I think we're going to buy a stationary bike.
